I have created an account on ArkhamDB and I have started to create a deck, but I am noticing that I only have for certain cards the ability to put one card in the deck. For example, for Dr. Milan Christopher I want to insert two copies, but the program only allows me to insert 1. I see other decks on ArkhamDB with two copies of CM and I can not figure out what I am doing wrong. Does anyone have a suggestion?

This comes about because, by default, ArkhamDB assumes you only have 1 copy of the core set.

Once you are logged in, click the "user" button (little meeple) in the top right. From the drop down menu, select "my collection". Make sure all products you own are selected, and select the little "2" next to "Core Set", then save.
